There are a lot of factors that go into something like this, but I really think it’s natural for anyone involved in the high-end realm to focus too much on the audio quality, whether intentionally or not. Also, some of us have put together systems that are much more resolving (brighter?) than our old ones and the flaws stick out more. That said, I’m very happy to say that the other night I pulled out my Sundazed reissue of the Vanilla Fudge first record and, horrendous audio quality aside, listened all the way through, without giving a thought to the audio aspect. My hearing is probably not over 12k anymore, but I really feel I was able to appreciate the music the way I did in high school, albeit with a different perspective on life. It's possible that the audio quality was SO bad, nothing could be done to salvage it, so there was no sense thinking about anything but the music. I don't know.
